Glutathione
In stockGSHEndogenous tripeptide gamma-L-glutamyl-L-cysteinyl-glycine, the most abundant low-molecular-weight thiol in mammalian cells. Researchers study its roles in redox homeostasis and signalling.
Supplied as a single-chamber lyophilized vial with a colour-coded cap (Anti-Aging).
Research literature, not dosing or treatment instructions.
- Glutathione is present in all mammalian tissues as the most abundant non-protein thiol, and reviews describe its role in defence against oxidative stress and in redox signalling. (PMID 22995213, PMID 18796312)
- Its biosynthesis occurs in the cytosol in a tightly regulated manner, with the supply of cysteine as a key determinant. (PMID 22995213)

Questions about Glutathione
How much published research is there on Glutathione?
The research library's PubMed search for Glutathione returned 316 records on 5 October 2026, 316 of them reviews. The library lists 3 studies chosen for what they measured.
Is Glutathione an approved medicine?
No centrally authorised medicine containing Glutathione is listed in the EMA medicines database (checked 5 October 2026), and the research material we supply is not a medicine. The EMA medicines database (checked 5 October 2026) lists no centrally authorised medicine naming Glutathione as an active substance. National authorisations are not in that dataset. Drugs@FDA lists two applications for ophthalmic irrigation solutions that contain glutathione disulfide among several ingredients. They are not applications for glutathione as a peptide medicine. It is supplied for in-vitro laboratory research only, not for human or veterinary use.
Is glutathione a peptide?
Yes, a tripeptide of glutamate, cysteine and glycine, linked through the gamma-carboxyl group of glutamate, with a free thiol on the cysteine residue. Reviews describe it as the most abundant non-protein thiol in mammalian tissues (PMID 22995213).
How is the identity of Glutathione confirmed on a certificate?
A research-grade certificate of analysis typically reports identity by mass spectrometry and purity by HPLC. The mass result is read against the average molecular weight of 307.3 Da listed on this page. The research library's guide to reading a certificate explains each field.
What other names is Glutathione published under?
Glutathione is also written GSH, reduced glutathione, Glutathione and reduced. The catalog lists it under the name Glutathione.
Is this product for human use?
No. Peptency products are supplied for in-vitro research only. Not for human or veterinary use, not for diagnosis or therapy.

What is Glutathione?
Glutathione is the endogenous tripeptide gamma-L-glutamyl-L-cysteinyl-glycine, the most abundant low-molecular-weight thiol in mammalian cells. Reviews describe its roles in redox homeostasis, detoxification and signalling. We supply Glutathione as a lyophilized vial for in-vitro laboratory research only.
What are the chemical identifiers of Glutathione?
Glutathione has the molecular formula C10H17N3O6S, an average molecular weight of 307.3 Da and CAS number 70-18-8.
Chemistry checked against PubChem (CID 124886), 5 October 2026; full chemistry record in the research library.
What does published research on Glutathione cover?
A PubMed search for Glutathione returned 316 records on 5 October 2026, 316 of them reviews. Our research library lists 3 of these studies, chosen for what they measured.
- Glutathione is present in all mammalian tissues as the most abundant non-protein thiol, and reviews describe its role in defence against oxidative stress and in redox signalling. (Lu, Biochim Biophys Acta, 2013; PMID 22995213; Forman et al., Mol Aspects Med, 2009; PMID 18796312)
- Its biosynthesis occurs in the cytosol in a tightly regulated manner, with the supply of cysteine as a key determinant. (Lu, Biochim Biophys Acta, 2013; PMID 22995213)
Mechanism, every cited study and the regulator records are on the Glutathione page of the research library. Papers are listed by what they measured, not as evidence of any use.
How is Glutathione supplied and stored?
Glutathione is supplied as a lyophilized (freeze-dried) powder in a sealed vial, for in-vitro laboratory research only. Our stated storage condition for the sealed lyophilized vial is 2 to 8 °C. The label and the lot certificate carry the lot-specific storage condition and expiry date.
What is the regulatory status of Glutathione?
The EMA medicines database (checked 5 October 2026) lists no centrally authorised medicine naming Glutathione as an active substance. National authorisations are not in that dataset.
The exact name appears in 1092 MHRA Products documents as text only, not as an active substance (checked 5 October 2026).
Drugs@FDA lists two applications for ophthalmic irrigation solutions that contain glutathione disulfide among several ingredients. They are not applications for glutathione as a peptide medicine.
A regulator record is information about a database entry. It is not advice and not a statement that any use is lawful or unlawful in any country. How regulators approach research peptides.
